We analyse the threats of global environmental change, as they relate to food security. First, we review three discourses: (i) 'sustainable intensification', or the increase of food supplies without compromising food producing inputs, such as soils and water; (ii) the 'nexus' that seeks to understand links across food, energy, environment and water systems; and (iii) 'resilience thinking' that focuses on how to ensure the critical capacities of food, energy and water systems are maintained in the presence of uncertainties and threats. Second, we build on these discourses to present the causal, risks and options assessment for decision-making process to improve decisionmaking in the presence of risks. The process provides a structured, but flexible, approach that moves from problem diagnosis to better risk-based decision-making and outcomes by responding to causal risks within and across food, energy, environment and water systems.

Citation of such a paper should account for its provisional character. A revised version may be available directly from the author. In this paper we utilise data from a unique new birth-cohort study to see how the risk preferences of young people are affected by cognitive skills and gender. We find that cognitive ability (measured by the percentile ranking for university entrance at age 18) has no effect on risk preferences measured at age 20. This is in contrast to experimental studies that use IQ measures to proxy cognitive skills. However we do find that gender matters. While young women are significantly more likely than young men to assess themselves as being prepared to take risks, women choose to invest significantly less when they are confronted with a clearly specified investment decision based on hypothetical lottery winnings. This difference between the impact of gender on risk attitudes and the hypothetical lottery investment suggests that impatience and framing affect young women and men differently.JEL Classification: D01, D80, J16, J24
